In yet another daring and deadly attack, Maoists Tuesday killed 26 security personnel, including 24 paramilitary troopers and an assistant commandant, in Chhattisgarh's restive Bastar region, officials said.

About a dozen personnel of the Central Reserve Police Force (CRPF) were also injured in the attack in Narayanpur district, state Home minister Nankiram Kanwar said.

"A joint contingent of over 70 men, mostly comprising CRPF troopers and some state police personnel, was ambushed by Maoists in a forested stretch in Narayanpur," an official at the police headquarters here told IANS.
